Circadian rest-activity rhythm in individuals at risk for psychosis and bipolar disorder

CONCLUSION:

The results suggest alterations in the circadian rest-activity rhythms (and likely in sleep-wake cycle patterns) in ARMS individuals compared with healthy controls. It is possible that circadian rhythms of activity and rest changes are one of the prodromal clinical and behavioral expressions of the brain changes that underlie ARMS individuals.

This is quite interesting. I read the short study after clicking the link, and I was intrigued by it. These findings definitely match my personal experience with psychosis and manic states over several decades, and I believe this is just more confirmation for what I now consider to be my warning signs. Thanks for the insightful thread. Good work.
